Example 141: List the Files in an IFS Directory (PHP)

Description:	This Example will demonstrate how to display and access the contents of a folder on the IFS.
	This example uses the opendir() and the readdir() PHP functions

'; } PANEL='listing' { DESC='listing segment'; DETAILS=' '; } PANEL='footer' { DESC='footer segment'; DETAILS='

Seq	File Name(Click on the file name to view or download)

Start with a \'A Simple Page PHP\' from one of the PHP template families.

Create two new segments, listing and footer.
(You can create new segment by choosing Attributes and then Segments from the menu)

Add this in between the <head> and </head> tags in the Main segment:

<style type="text/css">

    #row a:link {color:#000000;}
    #row a:hover {color:#fffff;}
    #row a:visited {color:#FF0000;}
  
</style>

Create a global variable: $filenum near the top of your PHP source code:
```
    global $filenum;
    				
```

Add the following code in the Main segment after the <div id="contents">

    <table>
    	<tr><td>Seq</td><td><Strong>File Contents</strong></td></tr>
    </table>

In the Main segment, cut everything after:

   <tr><td>Seq</td><td><Strong>File Contents</strong></td></tr>

and paste it into the footer segment

In the PHP source code replace the generic() function with this code:

function generic()
{
 wrtseg(\'MainSeg\');
 //put here your own folder e.g. opendir(\'c:\\\\temp\')
  if ($handle = opendir(\'/esdi/websmart/wsdemo/musicstore\')) 
   { 	
	$filenum = 1;
	while (false !== ($file = readdir($handle)))
	 { 		
      if ($file != "." && $file != "..")
	    {
	     if($filenum % 2 == 0)
		  {
		   $rowcol = "#C3C3C3";
		  }
 	     else
		  {
	       $rowcol = "#ffffff";
	      }
	echo "<tr id=\\"row\\" bgcolor=\\"$rowcol\\"><td>$filenum</td>
                 <td>
	          <Strong><a href=\\"/wsdemo/musicstore/$file\\">$file</a></Strong>
	        </td>
	      </tr>";
	         $filenum = $filenum + 1; 
	    }
			
	  }	
	wrtseg(\'listing\');		
    }
	
  wrtseg(\'footer\');
}
